The method of the component, a penetrating type ^1^.. L 牙思玉屏綦 and a rear projection projector. [Prior Art] In recent years, as a home theater monitor, a large-screen television, or the like (4), an appropriate display n has become increasingly demanding for a rear projection projector. to

In a transmissive screen for a rear projection type projector, a lens substrate having a plurality of lenses is generally used. Heretofore, a lenticular lens substrate having a lenticular lens has been commonly used as a lens substrate. However, the conventional rear projection projector having the lenticular lens substrate has a problem that although its lateral viewing angle λ, the vertical viewing angle is small (i.e., there is a deviation in the viewing angle). In order to solve this problem, an attempt has been made to use a microlens sheet (microlens substrate) on which a plurality of microlenses are formed to have an optical rotation symmetry (for example, see JP-A-2000-131506). . The lens sheet as described above is conventionally produced by using a method (for example, 'so-called 21> method) (specifically, the microlens substrate is in the 2ρ method, and the uncured resin is supplied in a plural number A plurality of lenses are formed on the substrate of the recesses, and the surface shape of the substrate with the recesses is transferred to the supplied resin (for example, see jp_A_2003-279949). However, 'there is a 2P method as described above--a problem: it is difficult The base is provided with a recess (4) to cure the resin. In addition, in the case of manufacturing a lens substrate (microlens substrate) having a microlens as a lens, the size of each of the (four) lenses is small (ie, 'lens' In the case of a fine structure) 106147.doc 1295382; in the case where the microlens substrate has a large number of lenses; forming a lens in a high density manner (for example, 1,000/cm2 or more) in the microlens substrate In the case of the lens substrate to be manufactured having a large area (for example, the substrate has a diagonal length of 60 cm or more), the problem becomes more conspicuous. Because this system: with a minute pattern formed on the surface of the concave portion of the substrate into a certain state, this state attributed to the anchor effect to be dependent on the manufacturing of the lens substrate.

Further 'existence-problem: when forcibly removing the substrate with the recess from the lens substrate, such as in a substrate with a recess and/or in any convex portion (convex lens) to be formed by means of transfer Defects in cracks. Therefore, due to the above-mentioned original purpose, there is also a problem that the yield of the lens substrate is extremely low.

Wherein, when viewed from above the light-emitting surface of the microlens substrate 1, its longitudinal width is greater than its lateral width. In the case t in which each of the microlenses 21 has the shape, it is possible to significantly improve the viewing angle characteristics of the transmissive screen 10 having the microlens substrate i while effectively preventing the occurrence of disadvantages such as ripples. In particular, in this case, it is possible to improve the viewing angle characteristics in the horizontal and vertical directions of the transmissive screen 10 having the microlens substrate 丨. When viewed from above the light incident surface of the microlens substrate 1, the length (or pitch) in the direction of each of the microlenses 21 in the short axis (secondary axis) thereof is defined as ί1 (μιη) and the microlens is In the case where the length (or pitch) of each of the major axes (spindle) directions is defined as "(μιη), the preferred ratio is in the range of ο·ιο to 〇·" (i.e., preferably L^L2 satisfies the relationship: 〇ι〇$ L!/L2 S 〇·99). More preferably it is in the range of 〇·5〇 to 〇95, and further preferably it is in the range of 0·60 to 0.80. By limiting the ratio of Li/L2 within the above range, the above effects are apparent. Preferably, when viewed from above the light incident surface of the microlens substrate 1, each of the microlenses 106147.doc 1295382 21 is on the minor axis. The length (or pitch) in the direction is in the range of (7) to. More preferably, it is in the range of 30 to 300 μπΐ2, and further preferably it is in the range of 50 to 100 μπι. In the case where the length in the direction of the minor axis is restricted within the above range, there is a possibility that the screen 1 to be penetrated A sufficient resolution is obtained in the image projected on 0 and the productivity of the microlens substrate 1 (including the transmissive screen 1) is further enhanced while effectively preventing the occurrence of defects such as ripples.

In the case of Ll_, '嶋丨 satisfies the relationship: o.2〇' l/Hm

Better Η#! Satisfaction relationship: 〇5 9, and further better H is full; UI system: G.9_<Li/Hq.4. In the case where _Li satisfies this relationship, it is possible to significantly improve the viewing angle characteristics while effectively preventing ripples due to interference of light. This multiplexes the plurality of microlenses 21 on the main substrate 2 in a dog-tooth lattice manner. By arranging a plurality of microlenses 21 in this manner, it is possible to effectively prevent the occurrence of disadvantages such as ripples. On the other hand, for example, in the case where the microlenses 21 are arranged on the main substrate 2 in a square lattice manner or the like, it is difficult to fill the blade to prevent the occurrence of disadvantages such as ripples. Further, in the case where the microlens is arranged on the main substrate 2, it is difficult to sufficiently increase the ratio of the area of the microlens 2 in the usable area in which the microlens 21 is formed, and it is difficult to sufficiently increase the area ratio. The light transmittance (light use efficiency) entering the microlens substrate 丨. In addition, the obtained image becomes dark. In the present embodiment, although a plurality of microlenses 21 are arranged on the main substrate 2 in a dog-tooth lattice manner when viewed from above one main surface of the microlens substrate, as described above, a plurality of microlenses 21 are preferably formed. A first row is translated by a half pitch relative to a second row 26 adjacent one of the first rows 25. This makes it possible to significantly improve the viewing angle characteristics while effectively preventing ripples due to interference of light. & As described above, by specifying the shape of each of the microlenses (convex portions) 21, the arrangement pattern of the microlenses 21, the area ratio of the microlenses 2, and the like, it is possible to significantly improve the viewing angle characteristics. At the same time, it effectively prevents the ripples from being caused by the light. Further, each of the microlenses 21 is formed as a convex lens that protrudes toward the light incident side thereof, and is designed such that its focal point f is located in the black matrix (near the opening 31 on the light shielding layer). In other words, each of the microlenses of the microlens substrate i will enter the parallel light La of the microlens substrate 1 from a direction substantially perpendicular to the direction of the microlens substrate ( (the parallel from the Fresnel lens 5 will be described later). The light La) condenses and focuses it on the focal point f provided in the vicinity of each opening 31 on the black matrix (light shielding layer) 3. In this way, since each of the light passing through the microlens 2 is light Focusing on the vicinity of each opening of the black matrix 3, it is possible to significantly enhance the light use efficiency of the microlens substrate. Further, since the light transmitted through each of the microlenses 21 is focused on the black matrix (light shielding layer) 3 Each opening - is adjacent to the opening 31, so it is possible to reduce the area of each opening. Further, it is preferable to view from above the light incident surface of the microlens substrate (i.e., in the direction shown in Fig. 2) Forming a microlens 2丨The ratio of the area occupied by all the microlenses 21 in the usable area (i.e., the available lens area) (the area projected) to the entire usable area is 90% or more. More preferably, the ratio is 96% or more. Preferably, the ratio is in the range of 97% to Μ·,. The ratio of the area # occupied by all the microlenses (convex lenses) 21 in the available area to the entire usable area is 9〇% or more. In the case, there is a possibility that the light is transmitted through the area other than the area occupied by the microlens 21' and this makes it possible to further enhance the light use efficiency of the through-hole screen 10 having the microlens substrate 1. In this aspect, when viewed from above the light incident surface of the microlens substrate 1, 'the center of the microlens 21 from the center of the microlens 21 to the area of the mountain Φ is formed (the microlens is not formed thereon) 2 1 4 106147.doc -18-1295382 The length in the direction of the center of the adjacent microlens 21) is defined as a claw, and the length of the center of the 4 Μ lens 21 and the center of the non-formed area is defined as Ε4 In the case of (μηι), the line segment can be The ratio of the length to the length of the line segment (i.e., LVL4 X 100 (%)) approximates the ratio of the area occupied by all the microlenses 21 in the usable area forming the microlens 21 (the area projected) to the entire available area ( Referring to Fig. 2). In this regard, the convex portion forming the second concave portion 62 corresponding to the member 6 with the concave portion (which will be described in detail later) is generally provided outside the usable lens region forming the microlens 21 as described above. After the main substrate 2 is obtained by means of a manufacturing method which will be described later, such convexity can be removed by means of, for example, grinding and polishing (corresponding to the convex portion of the second concave portion 62). Or, by The removable 幵 y is cut to correspond to the area of the convex portion of the second recess 62. In other words, the microlens substrate 1 may not have a convex portion corresponding to the second concave portion 62. Further, as described above, the colored portion 22 is provided on the microlens substrate! The light is incident on the surface (i.e., on the light incident side of each of the microlenses 21). Light from the light incident surface into the lens substrate 1 can be efficiently transmitted through the colored portion 22, and the colored portion 22 has a function of preventing reflection of external light to the light emitting side of the microlens substrate ι. By providing this coloring portion 22, it is possible to obtain a projected image with excellent contrast. In detail, in the present invention, the colored portion 22 is formed on the main substrate 2 by supplying a colored liquid (specifically, a colored liquid having a characteristic of a particular composition) (to be described later). In order to explain this particular feature in detail, the coloring portion 22 is injected into the main substrate 2 by supplying a coloring liquid (to be described later) on the main substrate 2 such that 106147.doc -19-1295382 in the coloring liquid is injected into the main substrate 2 ( Formed inside the microlens 21). In the case where the coloring portion 22 is formed in this manner, it is possible to improve the adhesion of the colored portion 22 as compared with the case where the colored portion 22 is laminated on one main surface of the main substrate 2. As a result, for example, it is possible to prevent a harmful influence on the optical characteristics of the microlens substrate, which is attributed to a change in refractive index in the vicinity of the interface between the colored portion 22 and the main substrate 2, without any error. Further, since the coloring portion 22 is formed on the main substrate 2 by supplying the colored liquid, it is possible to reduce the thickness variation of the respective portions (in detail, it does not correspond to the thickness variation of the surface shape of the main substrate 2). This makes it possible to prevent disadvantages such as color unevenness in the projected image. Further, although the colored portion 22 is composed of a material containing a coloring agent, its main component is substantially the same as that of the main substrate 2 (microlens substrate). Therefore, a rapid change in refractive index or the like is hardly produced in the vicinity of the boundary between the colored portion 22 and the other non-colored portion. As a result, it is easy to design the optical characteristics of the microlens substrate 1 as a whole, and it is possible to stabilize the optical characteristics of the microlens substrate and improve its reliability. The color density of the colored layer 22 is not particularly limited. Preferably, the color density of the color layer 22 indicated by the Y value based on the spectral transmittance (D65/2 viewing angle) is in the range of 2 〇〇 / 0 to 85%. More preferably it is in the range of 35% to 7%. In the case where the concentration of the coloring agent in the colored portion 22 is restricted to the above range, there is a possibility that the transmission of the microlens substrate is remarkably improved! The contrast of the image formed by the light. On the other hand, in the case where the color density of the colored portion 22 is lower than the lower limit given above, the light transmittance of the incident light is lowered and the obtained image cannot have sufficient twist. As a result, there is a possibility that the contrast of the image is insufficient. This 106147.doc -20- 1295382 externally, in the case where the color density of the colored portion 2 2 is still above the upper limit given above, it is difficult to sufficiently prevent reflection of external light (that is, entering the microlens from the side opposite to the light incident side) The substrate 1 is outside the light), and since the amount of the front side luminance of the black indication (black luminance) becomes large when the light source is completely turned off in the bright space, there is a possibility that the effect of improving the contrast of the projected image cannot be sufficiently obtained. The color of the coloring portion 22 of the uncle is that the color of the colored portion 22 is not specifically subjected to a color, especially a coloring agent in which the color is based on blue and lush, and brown or yellow is mixed therein.

Further, in the method of manufacturing the microlens substrate 1 to be described later, it is possible to more effectively prevent the member 6 with the recess and/or the microlens 21 from being attached. Defects such as cracks are generated. 106147.doc -27- 1295382 Part 1:: Number: The first recess 61 is arranged in a dog-toothed lattice with a concave and concave surface, and can be::? Arranging a plurality of first-months effectively prevents the occurrence of defects such as ripples. Another: =_ in a square lattice Or in a similar manner, in the case of generating a heart on a main surface, it is difficult to adequately prevent the disadvantages of being arranged in the corrugation. Further, the first recess 61 is arranged in a random manner in the attached ^

In the case of the fractional-first surface, it is difficult to fill the recessed portion 61 with the usable area of the first recess 61 (available through the middle and the μ (4), and the filament sufficiently improves the member of the money lens substrate 5 with the recessed portion The light transmittance (i.e., light use efficiency).

This makes it possible to make the lens substrate U main substrate 2) into a member with a convex portion. Self-attached with a concave core: 6, when the member with the convex portion (main substrate 2) is released, it is more effective to prevent any microlens 21 to be formed on the member with the concave portion 6 and/or the microlens substrate Defects such as cracks are produced. In addition, it is possible to significantly improve the viewing angle characteristics in the microlens substrate to be manufactured, and (iv) to effectively prevent the occurrence of waviness due to the interference of light. Now, in the case where a convex portion 1 having a large number of convex portions (convex lenses) corresponding to a large number of concave portions to which the concave member 106147.doc -28-1295382 is attached is manufactured using the member with the concave portion, there is a problem: It is difficult to release the member with the convex portion from the member to which the recess is attached. This is considered to be because the micro-pattern formed on the substrate with the concave portion becomes a certain state, which is attributed to the fixing effect of the lens substrate to be manufactured. In addition, when it is manufactured, it is attached with a convex. When the member of the crucible forcibly removes the member having the concave portion, there is a problem that (m: a member having a concave portion and/or a convex lens formed by changing the shape of the portion) such as a crack. Therefore, for the above reasons, it is also clear that the yield of the member with the convex portion is extremely low. Accordingly, = insist on a keen examination to solve the above problem. As a result, the present invention is directed to: the case where the member having the concave portion releases the member to which the convex portion is attached. The initial step (4) the stress of the concave member and the member with the convex portion is released ΰ γ (more specifically, The step of advancing the convex portion in the initial step is large, and after the convex portion from the concave portion releasing portion is completed, the stress is then lowered/integrated due to the formation of the convex portion corresponding to the to-be formed. Found, (the first region or the available region): mention = 7 each of the deep sounds, ~ u two recesses 'the second recesses have the P recesses (the recesses) - each of the deep production), =: :::= constitutive _ The condition of the member with a recess: There is a plaque that can be prevented even in repeated use of A 4 - January. In the present embodiment, in addition to the member 6 of the lift (for the & 〆, - recess 61, a recess is attached (i.e., a lens corresponding to the area of the microlens substrate 2 =: - recess 61) The first region of the domain 07) is externally W6147.doc -29- 1295382 has a plurality of second recesses 62. Further, it is believed that the first concave region 67 is formed in the middle of the body 6m - ", more, the body 5" The two end sides are in the longitudinal direction thereof (one of the ends corresponds to the member with the recessed portion, the cuckoo 9 is less stepped on the mountain, and the main substrate of the crucible 6 (with the configuration of the convex portion, the release starting side) Each of the sides is provided with a second region (non-available region) 68 in which the second recessed portion is formed. The first region in which the first recessed portion 61 is formed in this manner (4), the second recessed portion is provided on the release starting side 62 (second region 68), it is possible that when the member attached with the concave portion releases the main substrate 2, the stress absorbed to the structure with the concave portion 6 and/or the main substrate 2 to be formed enters the second concave portion 62. Forming (ie, 'the second region 68 of the member with the recess corresponding to the non-available lens region of the microlens substrate 1). Therefore, when released The formation of the first recessed portion (i.e., the 'first region 67') and the available lens region of the microlens substrate 1 is reduced, and therefore, it is possible to stably perform the release with a relatively small force. It is prevented that defects are generated in the concave/convex pattern of the member 6 with the concave portion and/or the main substrate 6. The gentleman, the right, and the fruit have a long life to extend the life of the member 6 with the concave portion.

In the microlens substrate (member with a convex portion) of the present invention of k, it is possible to effectively prevent the occurrence of a defect such as a crack of a concave-convex pattern, and the present invention: a lens substrate (a member with a convex portion) 1 In addition, this makes it possible to increase the productivity of the microlens substrate i. Although only the depth of each of the second recesses 62 is shallower than the mother of the first recesses 6 The depth is not special Restricted, but preferably each of the second recesses 62 has a depth in the range of 5 to 4 〇〇μπι per 106147.doc -30 - 1295382. More preferably, it is in the range of 15 to 15 ^, and Further preferably, it is in the range of 25 to 50 μη. In the case where the taste of the mother of the constraint is within the above range, it is possible to make the lens substrate 丨 (ie, the main substrate 2) as an attachment. The member having the convex portion is self-attached with a concave portion. When the member 6 having the convex portion releases the member with the convex portion (the main substrate 2), it is more effectively prevented from being in the member 6 with the concave portion and/or at the microlens substrate Defects such as cracks are generated in the microlens 21 to be formed. Further, the depth of each of the plurality of first recesses is defined as 〇1 (μΠ1) and the depth of each of the plurality of second recesses is defined as In the case of D2〇tm), 'better 〇1 and 〇2 satisfy the relationship: 3<Di_Dd 495. It is better to satisfy the relationship: 5 < D1 _ I 2 〇〇, and further better d#d2 satisfies the relationship: heart D1_D2 < 5G. In the case where the above-mentioned relationship is satisfied, it is possible to release the member with the convex portion from the member 6 to which the concave portion is attached in the member to which the microlens substrate i (i.e., the main substrate 2) is attached ( The main substrate 2) is more effective in preventing defects such as cracks in the member 6 to which the recess is attached and/or in the microlens 21 to be formed in the microlens substrate i. The size of each of the second recesses 62 when viewed from above the face is smaller than the size of each of the first recesses 61. In the case where the size of each of the second recesses is smaller than the size of each of the first-parts 61 in this manner, it is possible to effectively absorb the member in the vicinity of the second recess 62 to the recessed portion... or the main substrate 2 Further, in the present embodiment, the stress of the main table of the member 6 to which the recess is attached is self-contained, and it is possible to further achieve the above effects remarkably. Further, in the case where the size of each of the second recesses 62 is relatively small, the flaw may be reduced to the vicinity of the second recess 62. Therefore, it is possible to significantly improve the member 6 (in the vicinity of the second recess 62) having the concave 106147.doc -31 · 1295382 有, which is possible to significantly improve the resistance of the member 6 with the recess. As a result, the microlens substrate is improved! Productivity. Shaw. Further, it is possible that, in the present embodiment, in the second region 68 (i.e., the _ formation region), one of the main surfaces of the density recess 62 of the second recess 68 is attached with a recess from the main + field. When viewed above the surface of the component, the number of faces per unit is lower than the first recess in the first region 67 / = two: (d) This mode is the degree of the -A. By the way, the first recess 62 (the second region 6 has the above effect, and it is possible to improve the second recess c. Therefore, it is possible to change the shape of the parent of the right arm 2 to be stable. The durability of the member 6 with the recessed portion is improved to increase the yield of the microlens substrate 1. The second region of the second recess 62 is "closed to the second recess", but Preferably, in the second region 68, the second recess (four) is further in the range of 500,000 / (10) 2, more preferably in the range of 5 〇〇〇 to = 〇, 〇〇〇 W, and further More preferably, it is in the range of _ to 1M00 W. In the case where the second recess is constrained to have a density within the above range, it is possible to achieve the above effect more significantly. Thus, there is a possibility that each of the second recesses 62 can be improved. The shape stability of the person is likely to significantly improve the durability of the member 6 with the recess. The density of the recess 61 in the first region 67 is defined as a mountain (a / ') and the second region In the case where the density of the second recess 62 in 68 is defined as s/cm 2 ), it is preferable that di and d 2 satisfy the relationship: 0.001 $ di / d 〆〇 · 999 Di_2 more preferably satisfies the relationship: square 〇ι < and dl and d2 further more preferably satisfies the relationship: · 〇5 square < d " d "〇.80.

In addition, in the present embodiment, Yin Yi concave neighbor 61 > h γ ^ 歹 〗 〖 a concave. The crucible 62 is such that the second concave portion of the recessed portion 62 from the side of the member 6 to which the recess is attached is formed from the side on which the concave portion W61 is formed (i.e., the side of the _f £ domain 67). Sparse. This makes it possible to describe the effect. Therefore, it is possible to improve the shape stability of the mother of the second recess 62 and the durability of the member 6. "The shape of each of the second concave portions 62 having the concave portion is improved (the shape when viewed from a main surface to which the concave portion is attached) is not particularly limited. As for the shape, There are, for example, a circular shape in which the vertical length of each of the second concave (6) is greater than its horizontal length (including an enlarged circle), and the horizontal length of each of the central portions 62 is greater than its vertical length. The flat shape, in which the vertical and horizontal lengths thereof are randomly larger than the other, is flat. Further, the number of the second recesses 62 in the second region 68 is not particularly limited. In a linear manner (ie, in a general manner) The direction perpendicular to the release direction: linear) in the case where the second recess 62 is provided in the second region 68, the number of arrays of the second recess 62 preferably provided is about 1 〇 to 5 〇, 〇〇 Preferably, it is in the range of about 500 to 1 〇, 〇〇〇, and the further step is in the range of 2,000 to 5, _. This makes it possible to fully and significantly reach: The effect, while preventing unnecessary excessive amplification of the microlens substrate Lens region. Further, it is possible improvement of each strip portion 62 of the second recess 106147.doc -33- 1295382 stability, and it is possible with significantly improved durability of the recess 6 of the member.

Moreover, in the case where the second recess 62 is provided in the second region 68 in a linear manner (i.e., linear in a direction substantially perpendicular to the direction of discharge), the average spacing of two adjacent arrays of the second recess 62 Not specifically limited. For example, it is preferred that the average spacing of two adjacent arrays is in the range of 2 〇 to 1, 〇〇〇. More preferably it is in the range of 30 to 7 〇〇 μη ΐ 2, and further preferably it is in the range of 5 〇 to 500 μη ΐ 2 . The above effect can be more significantly achieved in the case where the average pitch of two adjacent arrays is constrained to 0 in the above range. Thus, it is possible to improve the shape stability of each of the second recesses 62, and it is possible to significantly improve the durability of the member 6 with the recesses. The length of the second region 68 in its release direction (i.e., the length indicated by ^ in Fig. 4) is not particularly limited. For example, it is preferred that the length of the second region 68 in the direction of release 5 is in the range of 20 to 5 〇〇 μη ΐ 2 . More pots are in the range of % to 350, and better in the range of 5q to the range of the beer. In the case where the length of the second region 68 in the releasing direction thereof is restricted within the above range, it is possible to sufficiently and remarkably achieve the above effects while preventing unnecessary excessive enlargement of the non-available lens region of the microlens substrate i. In addition, it is possible to significantly improve the durability of the member 6 with the recess. As described above, when the member attached to the concave portion (for manufacturing the microlens substrate) releases the microlens substrate (the member with the convex portion _, the second concave portion is called the second region), it is absorbed to the vicinity of the two The stress of the components. For this reason, it is possible to prevent the concave/convex pattern which breaks the formation region of the microlens. Therefore, the member 6 with the recess has a long life and excellent maneuverability. Further, by using the member 6 with the concave portion as a mold, it is possible to effectively 106147.doc -34 - 1295382 to prevent collision (fracture) or variation of the concave portion or the convex portion, and it is possible to be true.

The surface shape of the member to which the recess is attached is transferred to the microlens substrate i. It is possible to obtain a microlens substrate having excellent optical characteristics (a member with a convex portion). Further, it is possible to stably display a penetrating screen having such a microlens substrate (a member with a convex portion η) In the above explanation, it has been described that each of the first recesses 61 has and is supplied to the microlens substrate (member with the convex portion). Each of the microlenses (convex portions) 21 has substantially the same shape (size), and the first recesses _ have an arrangement pattern substantially the same as the arrangement pattern of the microlenses 21. However, for example, on the microlens substrate ( In the case where the constituent material of the main substrate 2 to which the convex member is attached tends to be easily contracted (that is, in the case of shrinking the resin (four) constituting the main substrate 2 by means of solidification or the like), Each of the microlenses (convex portions) 21 of the microlens substrate 1 and the shape (and size) and area of the first concave portion 61 provided to the member 6 with the concave portion (for manufacturing the microlens substrate 1) Ratio, etc. In addition, in this case, although in the conventional method (that is, in the method of using a conventional substrate with a concave portion), it is easy to have a member with a concave portion and/or a microlens. The substrate has the disadvantage of producing such as cracks, but in the invention, it is possible to effectively prevent the above disadvantages even in this case. Next, a method of manufacturing the member 6 with the recess according to the present invention will now be described with reference to Fig. 6. In the aspect, although the plurality of first recesses 61 and the plurality of second recesses 62 for forming the lenticular phantom are actually formed in the base member 7, in order to make the explanation understandable, one portion of the base member 7 is shown as 106147.doc - 35-1295382 is emphasized in Fig. 6. First, a base member 7 is prepared in the manufacture of the member 6 with the recess. Preferably, a base material having a substantially cylindrical or substantially cylindrical shape is used for the base member 7. Further, it is also preferable to use a base material with a surface cleaned by washing or the like for the base member 7. Although the constituent materials of the base member 7 may be mentioned: sodium Calcium glass, crystal glass, quartz glass, lead glass, potassium glass, bismuth borate glass, alkali-free glass and the like, but among them, soda lime glass and crystalline glass (for example, ceramic glass) are preferred. (neoceram or its analog). It is easy to process the material by using soda lime glass, crystal glass and alkali-free glass, and from the viewpoint of the manufacturing cost of the member 6 with the concave portion, because = glass or crystal The glass is relatively inexpensive, so it has an advantage. &lt;A1&gt; As shown in Fig. 6A, 'for forming a mask, a film μ is formed on the surface of the prepared base member 7 (coating process). The film 85 for forming a mask is used as a mask by forming a plurality of openings π (initial holes). Then, the film is formed on the back surface of the base member 7 (i.e., relative thereto). Forming the surface side of the surface of the film crucible used to form the mask). Needless to say, the film 85 for forming a mask and the back surface protective film 89 can be simultaneously formed. The constituent material of the film 85 for forming the occlusion (mask 8) is not particularly limited, and there may be mentioned, for example, metal such as Cr, heart, state, dicamba, and the like, which has k from this. Metal alloys of two or more metals of metals, oxides of such metals (metal oxides), resins and the like. Further, the film used to form the mask (mask 8) may be, for example, a film having a substantially uniform composition of 106147.doc - 36 - 1295382, a film of tantalum. ^Silk layer-layer structure: Γϊ = the structure of the film 85 forming the mask (mask 8) is not special; second: the film 85 forming the mask (mask 8) has a layered material formation The layer is composed of a layer of chromium oxide as the main layer 7. This structure is used for the shape: film 8: excellent stability with respect to various agents having various structures = it is possible to protect the substrate 7) more unambiguously in a process (to be described later), and It is possible to form the respective ones having a desired shape 81) by means of the irradiation of the laser beam and its like, which will be described later, more easily and without error. Further, in the case where the film 85 of the core forming material (mask 8) has the above-described structure, for example, a solution containing two hydrogen recordings (Shun Zen 2) may be appropriately used in the subsequent process (to be described later). It is used as a barrier. Because the solution containing Erden Hydrogen is non-toxic, it may be more correct to prevent the human body from affecting the environment and affecting the environment during work. Furthermore, this structure has a structure for forming a mask (mask 8) to make it possible to effectively reduce the stress inside the film for forming the mask (mask 8), and particularly to form a mask. (Mask 8) - the film 85 has excellent adhesion to the base member (i.e., 'in detail, the adhesion of the film 85 to the base member 7 for forming the mask (mask 8) in the engraving process) ). Therefore, by using the film stack for forming the mask (mask 8) having the above structure, it is possible to easily and without fail to form a plurality of first recesses 具有 having the desired shape. The method of forming the film 85 for forming the mask (mask 8) is not particularly limited. In the case where the film 85 for forming the mask (mask 8) is composed of any metal material such as Mb 106147.doc -37-1295382 (including a metal alloy) or a metal oxide such as an oxidation path, by means of (for example The evaporation method, the sputtering method, and the like can appropriately form the film 85 for forming the mask (mask 8). On the other hand, in the case of forming a thin reticle for forming a mask (mask 8), a mask (mask) can be suitably formed by means of, for example, an m-mine method, a CVD method, and the like. 8) Film 85. Although the thickness of the thin web 85 for forming the mask (mask 8) differs depending on the material constituting the film 85 for forming the mask (mask 8), it is preferably used for 7 The thickness of the film 85 which becomes the mask (mask 8) is in the range of _ to 2.0 _ and more preferably in the range of GW2_. If the thickness of the thin 臈 85 used to form the mask (mask =) is low The lower limit given above depends on the constituent material of the film 85 which forms the mask (mask 8) or the like, and may be formed in the initial hole forming process (or the opening forming process, which will be later The shape of the initial hole of the f· (the first initial hole 8 ι of the rumor) may be deformed (2) in the case of the masking portion of the base member 7 On the other hand, if the thickness of the film 85 used to form the mask (mask 8), the 'upper limit' is in addition to the initial hole forming process In addition to the difficulty of forming the initial hole 81 penetrating the mask 8 in the opening, it will depend on the film used to form the mask (mask 8) to form a material. The mask 8 is apt to be removed due to its internal stress. The moon-side protective film 89 is used to protect the base member 7 in the subsequent process. The back protective film 89 can appropriately prevent the back of the base member 7. 106147.doc -38- 1295382 Surface rot #, deterioration and the like. Because the back protection thorn has the same configuration as, for example, the film 85 used to form the mask, it can be similar to that used to form the mask The film 85 is formed in such a manner as to provide a back protective film (10) together with the formation of the film 85 for forming a mask. <A2> Next, as shown in the figure, in the etching process (described later) A plurality of first-initial holes 81 and a plurality of second initial holes 82 serving as mask openings are formed in the film 85 for forming a mask (initial hole forming is made). Thus, a pattern having a predetermined opening is obtained. Mask 8. Although the first initial hole 8 1 and the second are formed The method of the starting hole 82 is not particularly limited, but it is preferable to form the first initial hole 81 and the second initial hole 82 by irradiation of the laser beam, which makes it possible to easily and accurately form each having a desired shape and arranged in a desired pattern. The first initial hole 81 and the second initial hole 82. As a result, the shape of each of the first recess 61 and the second recess 62 can be controlled more unambiguously, and the arrangement pattern and the like. The beam irradiation forms the first initial hole 81 and the second initial hole 82, and it is possible to attach the concave member 6 with a high productivity. In detail, the concave portions can be easily formed on the relatively large-sized substrate. Moreover, in the case where the initial holes (including the first initial holes 81 and the second initial holes 82) are formed by irradiation of the laser beam, it is possible to form only the initial holes (including the first initial holes) by the irradiation conditions thereof. 8 1 and the first initial hole 82) without forming an initial recess (to be described later), or having an easy and error-free addition to forming the initial hole (including the first initial hole 81 and the second initial hole 82) Form its shape, size and depth The initial recess (the first initial recess 71) of which the change is small. In addition, by forming the first initial hole 81 and the second 106147.doc -39-1295382 initial hole 82 in the film 85 for forming the mask by means of a laser beam, it is possible to In contrast to the case where the opening is formed in the mask, it is easy to form the openings (the first initial hole 81 and the second initial hole 82) in the film 85 for forming the mask at a low cost.

Further, in the case where the first initial hole 81 and the second initial hole 82 are formed by irradiation of a laser beam, although the type of the laser beam used is not a specific cross, there may be mentioned: ruby laser, semiconductor laser , YAG laser, femtosecond laser, glass laser, YV〇4 laser, Ne_He laser, Ar laser, carbon monoxide laser, excimer misalignment and similar laser. In addition, waveforms such as SHG (second harmonic oscillation), THG (third harmonic oscillation), fhG (fourth harmonic oscillation), and the like can be used. As shown in FIG. 6B, when the first initial hole 81 and the second initial hole 82 are formed in the film 85 for forming a mask, in addition to forming the first initial hole 81 and the second initial hole 82, The first initial recess 71 and the second initial recess 72 may also be formed in the base member 7 by removing portions of the surface of the base member 7. This makes it possible to increase the contact area of the base member 7 with the etchant when the base member 7 with the mask 8 is subjected to an etching process (to be described later), whereby corrosion is appropriately started. Further, by adjusting the depth of each of the first initial recess 71 and the first initial recess 72, it is also possible to adjust the depth of each of the first recess 6 i and the second recess (ie, the lens (microlens 21) In addition, in the present embodiment, as shown in FIG. 6, the initial recess 71 is formed only by the portion corresponding to the first recess 6 (ie, the first initial hole 8). On the same day, the portion corresponding to the second recess 62 (i.e., the second initial hole 82) is not formed with the initial recess. Thus, it is possible to easily and unambiguously make the difference 106147.doc -40 - 1295382 of the depth of each of the first recesses 61 and the depth of each of the second recesses 62 relatively large. By controlling the conditions of the field, it is possible that the initial recesses may or may not be formed by the ', ,, and.

= The depth of each of the first-initial recesses 71 is not particularly limited, but is also soil, which is 5·〇 _ or less, more preferably in the range of the array. In the case where the formation of the first initial hole 81 and the second initial hole 2 is performed by irradiation of the laser beam, it is possible to reduce the first initial concave portion formed together with the first initial hole 81 and the second initial hole 82 without any error. ^ The change in depth of each of them. This makes it possible to reduce the variation in the depth of each of the members constituting the recessed portion 6 by the recesses, so it is possible to reduce the size of each of the microlenses 21 in the finally obtained microlens substrate i. With the change of shape. As a result, in detail, it is possible to reduce variations in lens diameter, focal length, and thickness of each of the microlenses 21. The shape and size of each of the first initial holes 81 to be formed in the present process are not particularly limited. In the case where each of the first-initial holes 81 is substantially circular = the first diameter of the preferred initial holes 81 is in the range of 〇 8 to 2 。. More preferably it is in the range of U to 1 〇 μη ΐ 2, and further preferably it is in the range of 1-5 to 4 μηη. In the case where the diameter of each of the first initial holes 81 is constrained within the above range, it is possible to form the first concave portions each having the shape as described above without fail in an inscribed process (to be described later). 61. On the other hand, in the case where each of the first initial holes 81 is a flat shape such as a substantially elliptical shape, it is possible to replace its diameter with a length in the short axis direction (i.e., its width). That is, in the case where each of the first initial holes 81 to be formed in the present process is substantially elliptical, although the width of each of the initial holes 81 (the length in the short axis direction) is not Special 106147.doc -41 - 1295382 are limited, but the width of each of the first initial holes 81 is in the range of 〇8 to 2〇. More preferably, it is in the range of 1 〇 to 1 〇 μιη, and further preferably it is in the range of 1.5 to 4 μηη. In the case where the width of each of the first initial holes 81 is restricted within the above range, it is possible to form the first recesses 6 each having the shape as described above without fail in an etching process (to be described later). 1 〇

Further, in the case where each of the first initial holes 81 to be formed in the process is substantially elliptical, although the length of each of the first initial holes 81 (the length in the long axis direction) is not It is specifically limited, but the width of each of the first initial holes 81 is in the range of 0.9 to 5 〇 μηη. More preferably, it is in the range of 15 to 20 Å, and further preferably in the range of 2 〇 to 15 _ in the case where the width of each of the first initial holes 81 is restricted within the above range, it is possible The first recess 61 each having the shape as described above is formed more unambiguously in a scribe process (to be described later). On the eve of the present invention, the first initial aperture 81 and the second preliminary aperture 82 can be formed in the coated film 85 for forming a mask by means of the following: (for example) when Coating the film for forming the mask on the base member 7 by arranging the foreign object on the base member 7 in advance in a predetermined pattern, and then coating the base member 7 for forming the thinner material (10) on the article Defects are formed in the mask 8 by design such that the defects are used as the first initial hole 81 and the first: initial hole 82. In this aspect, in the configuration as shown in FIG. 6, even if it has been described that the initial concave portion is formed only in a portion corresponding to the first concave portion 61 (ie, the first initial hole 81), the initial concave portion may correspond to the second portion. The recess Μ (ie, the second initial hole is called 106147.doc - 42 - 1295382 is formed. In this case, the first initial recess 71 corresponding to the first recess 6 丨 (ie, the first initial hole 81) The depth, shape, and the like of each may be different from the depth, shape, and the like of each of the second initial recesses corresponding to the second recess 62 (ie, the second initial aperture 82). For example, corresponding The depth of each of the second initial recesses of the first recess 62 may be shallower than the depth of each of the first initial recesses 71 corresponding to the first recess 61. &lt;A3&gt; Next, as in Figure 6 It is shown that a mask 8 is coated with a resist, a sealing member (band) 88 to the region (corresponding to a second region forming the second initial hole 82). 八4&gt; The member 7 is subjected to an etching process (etching process). The process is not particularly limited, and Mention may be made, for example, of a wet engraving process, a dry engraving process, and the like. In the following explanation, a case of using a wet etching process will be described as an example. First, a mask is applied. The base member 7 and the sealing member (10) having the first initial hole 81 and the second initial hole 82 are subjected to an etching process (in this case, a wet residual process). Thus, as in the drawing It is shown that the money is engraved at the portion corresponding to the base member 7 of the first initial hole 81 of the mask 8 while the etching is not performed at the portion where the mask 8 is coated with the sealing member. In the method of the (four) process The sealing member 88 is then removed. Thus, the remainder also begins at the portion of the mask 8 that is coated with the sealing member 88, and as shown in FIG. 6E, the first concave state and each of the base member 7 are formed. A second recess 62 having a depth that is shallower than the depth of each of the first recesses 61. As mentioned above, in the present embodiment, since 106147.doc -43- is formed in the mask 8. 1295382 The first initial hole 81 is arranged in a dog-tooth lattice, so it is to be formed The first concave portion 61 is also arranged in a dog-tooth lattice manner on the surface of the base member 7. Further, the second initial concave portion 82 formed in the mask 8 has a density lower than that of the first initial concave portion μ, and the second initial arrangement The recess 82 gradually becomes sparse in order to make the outer portion of the base member 7 of the mask 8 toward the mouth. Therefore, the second recess 62 to be formed has a lower density (four degrees) than that of the first recess 61, and the second recess 62 is arranged. In order to gradually become sparse to the outside of the base member 7. Further, in the present embodiment, when the step &lt;Α2&gt; is formed in the film 85 for forming a mask, the first initial hole 81 and the second are formed. The first initial concave is formed on the surface of the base member 7 at the time of the initial hole. This causes the contact area of the base member 7 and the etchant to increase during the (four) process, whereby the rot can be appropriately started. The first recess 61 and the second recess 62 can be appropriately formed by using the wet-type process. . In the case of (4) in which silver engraving agent containing, for example, dichlorohydrin is used as the etching d, the substrate member 7 can be more selectively smeared, and this makes it possible to appropriately form the first concave portion 61 and the second concave portion 62. . / The difluorohydrogen recording solution in which the mask 8 is mainly composed of chromium (i.e., composed of a material containing (4) as a main material) is particularly suitable as a hydrofluoric acid-based remnant. Because the winter 〆α 、,, and a solution of sputum ammonium are non-toxic, it is possible to prevent it from affecting the human body during work and on the environmental group.

The shirt is ringing. Further, in the case where A-gas Λτ A is used as an etchant, the etchant may contain, for example, chlorine peroxide. This makes it possible to accelerate the remnant speed. In addition, the vehicle master can perform the wet stenciling process in a simpler apparatus for dry splicing, and it allows a large number of base members 7 to be processed. This makes it possible to add a member with a recess to the member to which the recess is attached 106147.doc - 44 - 1295382. It is possible to produce a car and it is possible to remove the mask 8 (mask removal f 耘) as shown in Fig. 6F. At this time, along with the mask 8, a spleen north ^ ^ cut surface protective film 89 is removed. In the case of the self-material opening ^ is the main (four) morphing layer and the layered structure composed of chrome oxide as the main = layered layer _ in the case, can be used to help the use of cerium ammonium nitrate and the mask The removal of 8 . . . "the object of the engraving process is as shown in the figure π, Figure 4 and Figure 5, the result of the above process is obtained - the member 6 with the concave portion, in which the canine-shaped large teeth lattice A plurality of second recesses 62 are formed on the outer surface of the region in which the first recess is formed in the base member 7. The plurality of second recesses are formed on the surface of the base member 7. The method of the recess 62 is not particularly limited. In the form of a crescent of the lattice shape of the first recessed portion 61 and the second recessed portion 62 by means of the above-described method, that is, by irradiation with a laser beam Forming a first initial hole and a second initial hole 82 in the mask-forming film 85 to obtain a mask 8 on the base member 7, and then forming the first member 7 in the base member 7 by subjecting the base member 7 to an etching process using the mask 8. In the case of a method of a recess 61 and a second recess 62, it is possible to obtain The column effect. That is, by forming the first initial hole 81 and the second initial hole 82 in the film for forming the mask by means of the laser beam to obtain the mask 8, it is possible to use the conventional light lithography The method is easy and inexpensive to form an opening in a film 85 for forming a 106147.doc -45 - 1295382 mask in a predetermined pattern as compared with the case of forming a mask in the film forming the opening (first initial aperture) And a second initial hole 82). This makes it possible to increase the productivity of the member with the recess, whereby it is possible to provide the member 6 with the recess at a lower cost. Further, according to the above method, it is possible to easily implement The processing of a large-sized substrate. Also in the case of manufacturing a large-sized substrate according to the present method, there is no necessity of soldering a plurality of substrates as in the conventional method, whereby it is possible to eliminate the appearance of the welded seam. This makes it possible to resort to a simple method at a low cost.

袈达回. The large size of the stomata is used to form the member 6 with the concave portion of the microlens 21 (i.e., the microlens substrate 1). Further, in the case of the illumination of the clock beam &amp; the first initial aperture 8ι and the second initial aperture 82, it is possible to easily and without error control the first-initial aperture 81 and the second initial aperture 82 to be formed. The shape and size, arrangement and similar features of each. Further, by using the sealing member 88 in the etching process, it is possible to easily and unambiguously form the concave portion 61 and the second concave portion 62 whose depths are different from each other. Further, it is possible to easily and unambiguously control the depths of the first concave portion η and the second concave portion 62 to be formed. Next, a method of manufacturing a microlens substrate (member with a convex portion) 1 using the member 6 with a concave portion will now be described. Fig. 7 is a longitudinal cross-sectional view schematically showing an example of a method of manufacturing a microlens substrate (microlens substrate) shown in the drawing. Now, in the explanation below using FIG. 7, for convenience of explanation, the lower side and the upper side in the figure will be referred to as "light incident side, and, light-emitting side", respectively, as shown in the figure. As shown in FIG. 7A, a resin material 106147.doc -46-1295382 23 (for example, a resin material 23 in a softened state, a non-polymerized (uncured) resin material 23) having a flowing tenth is supplied thereto to form a first A recess 61 and a second recess are attached with the surface of the member 6 of the recess #, and then the resin material 23 is pressed by means of the flat plate 11. In detail, in the present embodiment, the flat u is pressed (or pushed) ), the grease material 23' simultaneously provides a space between the member 6 with the recess and the flat plate u, so that it is possible to control the degree of dryness of the formed microlens substrate 1 more unambiguously and this allows for more controllable control The focus of the respective microlenses 21 in the finally obtained microlens substrate i. In addition, it is possible to more effectively prevent the occurrence of defects such as color unevenness. Refraction by having a resin material 23 (resin material 23 in a solidified state) which is almost equal to Rate of refractive index Each of the spacers is formed. By using the spacer 2 formed by the material, it is possible to even form any of the first recesses of the member 6 with the recesses formed therein in the spacer 20 In the case of part of the 'preventing spacer 2 产生 has a detrimental effect on the microlens substrate characteristics obtained. This makes it possible to provide a relatively large number of spacers 20 in a wide area of one of the main surfaces of the member 6 to which the recess is attached. As a result, it is possible to effectively remove the influence due to the deflection of the member 6 and/or the flat plate η with the concave portion or the like, and this makes it possible to control the thickness of the obtained microlens substrate 1 more without fail. Although the spacer 20' is formed of a material having a refractive index almost equal to the refractive index of the resin material 23 (the resin material 23 in a solidified state) as described above, more specifically, it is preferably a constituent material of the spacer 2 The absolute value of the difference between the absolute refractive index and the absolute refractive index of the resin material 23 in a solidified state is 0.20 or less, and more preferably 〇1 〇 or less. Further, the resin material of 106147.doc _47· 1295382 is preferably a spacer 2 which is preferably formed of the same material as that of the material 23 in the solidified state. The shape of each of the spacers 20 is not specifically limited. Preferably, each of the spacers 20 is generally spherical or substantially cylindrical in shape. In the case where each of the spacers 20 has such a shape, it is preferable that the scale of the spacer 2 is in the range of 1 〇 to (4), and more preferably it is further preferably in the range of 30 to 200 Å. It is in the range of 30 to 1 70 μm.

In this regard, in the case of using the above-described spacer 2, when the resin material 23 is cured, the spacer 20 can be provided between the member 6 to which the recess is attached and the flat plate u. _, the timing of supply and supply of spacers is not specifically limited. Further, for example, a resin material in which the spacer 2 is previously dispersed can be utilized. As the resin material 23 supplied onto the surface of the member 6 with the recessed portion on which the first recess 61 is formed, or the resin material 23 may be simultaneously supplied on the surface of the member 6 to which the recess is provided on. Alternatively, the spacer 20 may be supplied onto the surface of the member 6 to which the recess is attached after the resin material is supplied thereon. The resin material 23 is usually formed of a material corresponding to the constituent materials of the above-described main substrate 2. Further, 'for example, the resin material 23 may include: a polymerization initiator, a hardening anti-sticking agent (for example, an 'amine-based compound), a dispersing agent, a solvent, a diffusing agent (for example, a bead glass, a vermiculite, an inorganic base). Oxides, inorganic carbonates, inorganic sulfates, organic resins and the like), ultraviolet absorbers, light stabilizers, surfactants, defoamers, antistatic agents, oxidation inhibitors, flame retardants and Its kind of stolen goods. For example, in the case where the blush material includes a diffusing agent, it is possible to improve the viewing angle characteristics of the transmissive screen 10 to which the microlens substrate 应用 is applied as described above. In addition, for example, because even if the configuration of the diffused 106147.doc -48-1295382 board or the like is neglected, it is possible to improve the viewing angle of the screen of the penetrating screen. The screen (7) and/or the rear projection machine 300 are thinner. Further, in the present invention, when the resin material 23 is coated on the member 6 to which the recess is attached, a member 6 for assisting the microlens substrate 1 with the recess is provided at one end portion of the member 6 to which the recess is attached. The member 69 is released, and the resin material 23 is applied to the member 69. In the case where the member 69 is used when the resin material 23 is supplied (coated) on the member 6 to which the recess is attached in this manner, it is possible to release the main substrate 2 in the subsequent process (i.e., from the member 6 to which the recess is attached) In the process, the vicinity of one end portion of the main substrate 2 to be formed is gripped without fail by removing the member. As a result, it is possible to prevent the addition of relatively large stress to any second recess 62 and any corresponding convex portion of the main substrate 2 in the process of releasing the main substrate 2 from the member 6 to which the recess is attached, and it is possible to start more smoothly. And the release of the main substrate (the member with the convex member) 2 is performed. In addition, it is possible to improve the shape stability of each of the second convex portions 62 and it is possible to remarkably improve the durability of the member 6 with the concave portions. Although the member 69 may be formed of any material, the adhesive force of the preferred member to the resin material 23 (i.e., the resin material η solidified after being supplied thereto simultaneously has fluidity) is smaller than the member 6 to the resin material U having the recessed portion. Stickiness. The width of the member 69 (the length of the member in the release direction of the main substrate 2, that is, the length indicated by L6 in Fig. 7A) is not particularly limited. For example, the preferred member 69 has a width in the range of 〇.5 to 2 〇〇 mm. Better in the range of $ to 106147.doc -49- 1295382 100匪, and the better step is better! 〇 to the range of 50 mm. In the case where the width of the member 69 is constrained within the above range, it is possible to sufficiently and remarkably achieve the above effects while preventing more than necessary magnification of the non-available lens region of the microlens substrate 1. In addition, it is possible to improve the shape stability of each of the second projections 62 and further it is possible to significantly improve the durability of the member 6 with the recesses.

Further, a release agent or the like may be coated on the surface of the member 6 on which the recessed portion of the first recess 61 and the second recess 62 is formed and/or applied to press-extrude the resin material 23 On the surface of the plate n. This makes it possible to separate the microlens substrate 1 (main substrate 2) from the member 6 with the concave portion and the flat plate u easily and without mistake in the following steps. As for the release process, formation of a film formed of a material having mold release ability, there may be mentioned, for example, a fluorine-containing organoantimony compound, a ruthenium-based compound such as an alkyl polysiloxane, such as polytetrafluoroethylene. Fluorine-based compound and alkyl quaternary ammonium salt; surface treatment by means of a decylating material from a decylating agent such as hexamethyldiazepine ([(CH3)3Si]2NH), by means of fluorine Surface treatment of the gas or the like. &lt;B2&gt; Next, solidification (in this aspect, including hardening (polymerizing) resin material 23' and then removing the flat plate 11 (refer to Fig. 7B). In this way, it is obtained to have a plurality of microlenses 21 (in detail, satisfied The main substrate 2 of the microlens 21 such as the shape, the alignment condition, and the like as described above, the microlens 21 is composed of a resin material 23 filled with a plurality of first recesses 61 each serving as a convex lens. In the case where the solidification of the resin material 23 is carried out by hardening (polymerization), the method thereof is not particularly limited, and the method is appropriately selected depending on the kind of the resin material. For example, there may be mentioned, for example, ultraviolet light. Irradiation, heating, electron beam irradiation, and the like. By solidifying the resin material 23, in addition to forming the microlens 21, a convex portion corresponding to the second concave portion 62 is also formed. The convex portions may be removed by the microlens substrate 1. Alternatively, the convex portions may serve as lenses. In this respect, the hardness of the cured resin material 23 is preferably a Shore D hardness of 80 to 20 In scope, and better In the case of a Shore d hardness of d 6 〇 to 30. In the case where the hardness of the resin material 23 is restricted within the above range, the main substrate (member with a convex portion) 2 may have sufficient hardness. And it is possible to suppress an increase in stress when the main substrate 2 is released from the member 6 with the concave portion as a mold. Further, it is possible to significantly improve the stability of the concave-convex pattern of the main substrate 2 (i.e., its shape stability) &lt;B3&gt; Next, a process in which a black matrix 3 is formed on the light-emitting surface of the main substrate 2 manufactured as described above will now be described. First, as shown in Fig. 7C, light emission on the main substrate 2 A positive type photopolymer 32 having a light shielding (blocking) effect is supplied on the surface. Regarding the method of supplying the positive type photopolymer 32 on the light emitting surface of the main substrate 2, the following various types of coating methods are available. (for example): a dip coating method, a knife coating method, a spin coating method, a glazing coating method, a spray coating, an electrostatic coating, an electric ore coating, a roll coater, and the like, which can have a light shielding (blocking) effect. Resin group: positive type photopolymer 32' or from there, a material having a light-shielding (blocking) effect 1 material dispersed or dissolved into a resin material having a low light-shielding (blocking) effect constitutes a positive type photopolymer 32. If necessary, After the positive type of light «32, the heat treatment of the pre-baking process is carried out, for example. '... (10) Secondly, as shown in 'Please show' the light to be used for exposure (10) - vertical 106147.doc -51 - 1295382 straight to the main substrate 2 The direction of the light incident surface is irradiated onto the main substrate 2. The positive type of light collected near the coke of each of the microlenses 21 is exposed by the illumination light for exposure through the microlenses 21 The body type, and does not expose the first or weak exposure (i.e., 'small exposure degree') corresponds to the positive type photopolymer 32 except for the focus. In this way, only the positive type photopolymer 32 near the respective focal point f is exposed.

Development is then carried out. In this case, since the photopolymer 32 is a positive type photopolymer, the exposure photopolymer 32 in the vicinity of the respective focus f is removed by development and removal. As a result, as shown in _, a black matrix 3 in which a portion which is opened (10) to the optical axis L of the wide microlens 22 is provided. The developing method can be arbitrarily selected in accordance with the composition of the positive type photopolymer 32 or the like. For example, development of the positive type photopolymer 32 in this embodiment is carried out by preparing an aqueous solution of a solution such as potassium hydroxide or the like. In this manner, in the method of manufacturing the microlens substrate 本 of the present embodiment, since the black matrix 3 is formed by irradiating the photopolymer 32 with light for exposure condensed by the plurality of microlenses 21, it is possible ( For example, the black matrix 3 is formed in a simpler process than in the case of using the photolithography technique. Further, if necessary, after the positive type photopolymer 32 is exposed, a heat treatment such as a post-baking process may be performed. &lt;B5&gt; Next, the main substrate (the member with the convex portion) 2 is released from the member 6 to which the concave portion is attached. First, as shown in Fig. 7F, the member 69 is separated from the autonomous substrate 2 by removing the member 69 from the member 6 to which the recess is attached. This results in a distal end portion of the main substrate 2 corresponding to the member 69 to a state in which the member 6 of the recessed portion 106107.doc - 52 - 1295382 is separated. By using the member 69 in this manner, it is possible to grip the end portion of the main substrate 2 to be formed, the last name, the sigma, the σ fruit, and it is possible to effectively prevent the addition of relatively large stress to the member with the convex portion. Any second recess 62 of the member 6 with the recess and/or the vicinity of any corresponding protrusion. In addition, it is possible to effectively prevent the addition of relatively large stress to any of the first recesses of the member 6 with the recess to be formed with the convex member to be formed, and it is possible to start and perform the main body more smoothly. The release of the substrate (the member with the convex portion) 2 is further improved. Further, it is possible to improve the shape of the second convex, and it is possible to significantly improve the durability of the member 6 with the concave portion. As shown in =7G, When the member to which the recess is attached is attached, the main substrate 2 is bent. When the member 6 to which the recess is attached releases the main substrate 2, each of the first recesses 61 in the member 6 of the release direction :::: The short axis of the second is such that it is possible to further reduce the depression to the recessed portion during the release. "2 stress, and it is possible to prevent the occurrence of the concave-convex pattern from the release of the member 6 with the concave portion In the case of the main substrate 2, the main substrate 2 is preferably discharged continuously (without interruption) in a large enthalpy. This causes an interruption, such that: in the re-starting of the emerald operation in which the release operation is present, the member is attached to the recessed portion...to the extent that the above effect is sufficiently achieved: the stress is increased' and thus 'The existence cannot be because of the above-mentioned 篦-如Μ", a 4 62 is provided in the member 6 with the recess, 106147.doc •53·1295382, and it is easy to use the relatively small force The member 6 with the recesses releases the main substrate 2 (while sufficiently preventing defects such as cracks in the concave-convex pattern). Although the release speed is not particularly limited, for example, the release speed f is preferably More preferably in the range of 0·1 to 500 mm/sec. It is preferably in the range of di〇〇mm/sec and further preferably in the range of 10 to 50 mm/sec. In the case of the range, the helium may perform the releasing operation more stably. On the other hand, in the case where the releasing speed is lower than the lower limit given above, the member 6 attached with the recess releases the main substrate 2 very expensive. Time, and therefore 'there is a microlens substrate 丨 (the main substrate hook Further, in the case where the release rate is higher than the upper limit given above, the stress to the member 6 with the recess and the main substrate 2 is increased, and thus there is a failure to fully achieve The possibility of the above effect. Although the force (tensile strength) at which the member 6 attached to the recess is released from the main substrate is not particularly limited, for example, the force (tensile strength) is preferably 5 to 1000 g. More preferably in the range of /-n (width), more preferably in the range of 8 to 7 〇〇g/cm (width), and even more preferably in the range of 1 〇 s 500 g/cm (width). By restraining the force (tensile strength) in the above range, it is possible to carry out the releasing operation more stably. On the other hand, in the case where the force (tensile strength) is lower than the lower limit given above, The release of the main substrate 2 by the member 6 with the recess portion is very time consuming, and therefore, there is a possibility that the productivity of the microlens substrate 丨 (main substrate 2) is low. Further, the force (tensile strength) is high. In the case of the upper limit given above, the member 6 and the main base to which the recess is attached are brought The stress of the plate 2 is increased, and therefore, there is a possibility that the above effects cannot be sufficiently achieved. 106147.doc • 54- 1295382 = This mode is obtained as shown in Fig. 7 and obtained as a black matrix 3 on its light emitting surface. The main substrate (the member with the recessed portion) 2, &lt;B6&gt; is connected by the supply-coloring liquid to the member having the recessed portion: the main substrate 2 that is released is formed with a coloring portion thereon Thereby, the microlens substrate 1 is obtained (see FIG. 71).

The coloring liquid is not limited, and in the present embodiment, the coloring liquid is a coloring liquid containing a coloring agent and a glycol. The present inventors have found that it is possible to carry out the coloring of the main substrate easily and without error by using this - coloring liquid. Specifically, according to the present process, it is possible to easily and unambiguously subject the main substrate 2 formed of a material such as a propylene-based resin to a coloring process which is difficult to color in a conventional coloring method. It is considered that the benzyl alcohol in the coloring liquid penetrates deeply into the main substrate 2 and diffuses therein, because the following original ▲ is used as the coloring liquid containing benzyl alcohol, thereby bonding the molecules constituting the main substrate 2 (The bond between the molecules) is loosened and the space in which the colorant will penetrate is fixed. The (4) and the coloring agent are replaced in the colored liquid, whereby the coloring agent is held in the work room (the seat (coloring seat) which can be compared to the coloring agent), and therefore, the surface of the main substrate 2 is colored. Further, by using the coloring liquid as described in ±, it is possible to form the coloring portion 22 having a uniform thickness easily and without iron. In detail, even if the main substrate to be colored (ie, working) is a main substrate in which a minute structure such as a microlens is provided on the surface thereof (one in which the unevenness of the two-dimensional direction of the surface thereof is smaller) The main substrate), or the main substrate in which the area to be colored is a large area, it is also possible to form the 106147.doc -55-1295382 colored portion 22 with a uniform thickness (i.e., no color unevenness). As for the method of supplying the coloring liquid on the light incident surface of the main substrate 2, there may be mentioned various coating methods such as, for example, a doctor blade method, a square coating method, a photo coating method, a spray coating, and the like. Electrostatic coating, electroplating coating, printing, roll coater and an impregnation coating method in which the main substrate 2 is immersed (soaked) in a colored liquid and the like. The impregnation method (in particular, impregnation dyeing) is suitable in these methods. This makes it possible to form the coloring portion 22) having the uniform thickness of the coloring portion just as easily and without error. Further, in detail, in the case where the colored liquid is supplied onto the main substrate 2 by means of 2-impregnation dyeing, it is possible to easily and unambiguously color the main substrate 2 formed of a material such as an acrylic-based resin, and this main substrate 2 It is difficult to color in a conventional coloring method. This is because the dye which can be used for the impregnation dyeing has a high affinity for the g group (g-bond) which the acrylic acid-based resin and the like have. The rutting κ applies a coloring liquid supply step while heating the colored liquid and/or the main plate in the range of 6 G ° C to 1 GG ° C. This makes it possible to effectively form the colored enamel 22, as well as sufficiently preventing the harmful influence on the main substrate 2 on which the coloring portion 22 is formed (for example, the constituent material of the main substrate 2 is deteriorated). In addition, the coloring liquid supply step can be applied while increasing the environmental pressure (should be pressure). This makes it possible to accelerate the penetration of the coloring liquid into the main substrate 2, and it is possible to effectively form the coloring portion 22 in a short time. In this respect, if necessary (for example, in the thickness phase of the colored portion 22 to be formed, in the iterative shape of the sub-layer), the coloring liquid supply step can be carried out repeatedly (i.e., multiple times). In addition, if necessary, after the supply of the coloring liquid, the main substrate 2, the heat treatment such as heating, cooling and the like, and the light irradiation 106147.doc -56-1295382 may be applied, and the pressure or pressure of the air pressure may be reduced. Pressure or similar steps. This makes it possible to accelerate the fixation (stability) of the colored portion 22. Hereinafter, the coloring liquid used in this step will be described in detail. The percentage of benzyl alcohol in the coloring liquid is not particularly limited. The percentage of the preferred alcohol content is in the range of 0.01 to 10.0% by weight. More preferably it is in the range of 0.05 to 8.0% by weight, and further more preferably it is in the range of 〇1 to 5.0% by weight. In the case where the content percentage of benzyl alcohol is confined within the above range, it is possible to form a suitable coloring portion 22 easily and without fail, while more effectively preventing generation of a detrimental effect on the main substrate 2 on which the coloring portion 22 is formed (such as The constituent materials of the main substrate 2 are deteriorated). Although the coloring agent contained in the color liquid may be any coloring agent such as various dyes and various pigments, it is preferred that the coloring agent be a dye. More preferably, it is a disperse dye and/or a cationic dye, and further preferably it is a dispersed dye. This makes it possible to effectively form the coloring portion 22 while sufficiently preventing the harmful influence on the main substrate 2 on which the coloring portion 22 is formed (e.g., the constituent material of the main substrate 2 is deteriorated). In particular, it is possible to easily and without error coloring even the main substrate 2 formed of a material such as an acrylic-based resin, which is difficult to color in a conventional coloring method. This is because the coloring agent as described above uses an ester group (ester bond) possessed by an acrylic resin and the like as a coloring seat, so that the material is easily colored. As described above, although the coloring liquid used in the present embodiment contains at least a coloring agent and benzyl alcohol, it is preferred that the coloring liquid further contains a compound selected from the group consisting of a benzophenone-based compound and a benzotriazole-based compound and a section. Alcohol = one less compound. This makes it possible to form the coloring portion 22 more effectively, while 106147.doc • 57·1295382 sufficiently prevents the harmful effects on the main substrate 2 on which the coloring portion 22 is to be formed (for example, the main 4πτ. The composition of the soil board 2 is deteriorated). This is considered to be due to the following reasons. That is, by using at least one compound containing a sterol and a compound selected from the group consisting of a benzophenone-based compound and a benzoquinone-based compound (hereinafter, benzyl alcohol, a diphenyl-based compound, and a benzotriazole-based compound) The compound is generally referred to as a coloring liquid of &quot;J, plus d, in which the additives penetrate into and diffuse in the main substrate 2, thereby bonding the molecules constituting the main substrate 2 (between molecules) The bond) is loosened, and the colorant is fixed in place of the colorant and the additive, thereby holding the colorant in the space (which can be compared to the seat of the coloring d (colored seat)), and Therefore, the surface of the main substrate 2 is colored. It is considered that this is because, by using together with benzyl alcohol, at least one compound selected from the group consisting of a benzophenone-based compound and a benzotriazole-based compound interacts in a complementary manner, and the colored liquid becomes more colored. it is good. As the benzophenone-based compound, a compound having a benzophenone main chain, a tautomer thereof or such an inducer (for example, an addition reaction product, a substitution reaction product, a reduction reaction product, or the like) may be used. Oxidation reaction products and their analogs). As the compound of 4, there may be mentioned, for example, benzophenone, 2,4-di-di-benzoicone, 2-hydroxy-4-methoxybenzophenone, 2,2,-dihydroxyl _4,4,-Dimethoxybenzophenone, tetrahydroxybenzophenone, 2-hydroxy-4-inocyl-methanone, 4-benzyloxy-2-perbenzyl-benzophenone-, two Benzophenone aniline, benzophenone oxime, benzophenone chloride (α,α'-dichlorodiphenylmethane) and the like 106147.doc -58-1295382. A compound having a benzophenone backbone in such compounds is preferred, and more preferably the compound is 2,2,-dihydroxy-4,4,4-dimethoxybenzophenone and 2'2,4 , any of 4-tetrahydroxybenzophenone. By using this compound based on benzophenone, the effects as described above are remarkably exhibited. In addition, as for the compound based on benzoquinone, there are compounds having a clumole triazole backbone, tautomers thereof or such inducers (for example, addition reaction products, substitution reaction products, reduction reactions) Product, oxidation reaction product and the like). As such compounds, there may be mentioned, for example, benzotriazole, 2·(2-hydroxy-5-methylphenyl)-2Η-benzotriazole, 2-(2-hydroxy-'octyloxyphenyl) _2η_benzotriazole and its analogs. A compound having a benzotriazole main chain among these compounds is preferred, and more preferably the compound is 2-(2-hydroxy-5-methylphenyl)_2Η_benzolazole and 2-(2-hydroxy-) Any of 4-oxooxyphenyl)-2Η-benzotriazole. By using this - a benzoquinone-based compound, the effects as described above are remarkably exhibited. In the case where the coloring liquid contains a benzophenone-based compound and a benzotriazole-based compound, the percentage of the total content of the compound based on the benzotriazole and the benzotriazole-based compound in the coloring liquid is not specifically affected. limit. Preferably, the percentage of the total content of the benzophenone-based compound and the benzotriazole-based compound in the colored liquid is in the range of from 1 to 1% by weight. More preferably, it is in the range of 0.005 to 5% by weight, and further preferably it is in the weight percentage of G.G1 to 3.G (IV). In the case where the percentage of the total content of the benzophenone-based compound and the benzoquinone-based compound is within the above range, it is possible to form a suitable coloring 106147.doc -59- 1295382 easily and without error. At the same time, it is more effective to prevent the occurrence of detrimental effects on the main substrate 2 on which the coloring (4) is to be formed (such as deterioration of constituent materials of the main substrate 2). Further, the coloring liquid contains a benzamidine-based compound and/or a benzoquinone-based compound, and the percentage of cerium-containing compound in the coloring liquid is defined as X (weight percentage) and will be based on The compound of benzophenone and the compound based on benzoquinone trisal are preferably in the case where the percentage of the coloring liquid is defined as Y (weight percent), and the ratio of X and γ is satisfied. Formula: 〇·〇〇m/γ q. Better Y turns to satisfy the relationship ·· 0.05 S X/YS i _, and the better step γ satisfies the relationship · ^ X/YS 5 00. In the case where X and γ satisfy the above relationship, synergistic effects are exerted more significantly by using a benzophenone-based compound and/or a benzoquinone-based compound together with the alcohol. In addition, it is possible to: form a suitable coloring portion 22 at a high speed, and prevent the harmful effects of the main substrate 2 on which the coloring portion 22 is to be formed (2:

The constituent materials are deteriorated). A I Further, it is preferred that the coloring liquid further comprises a cleavage and a surfactant. This makes it possible to stabilize the colorant even in the presence of (4). Even if the main substrate 2 on which the colored liquid is to be supplied is made of, for example, melamine, and the main substrate 2 is difficult to be colored in a conventional manner, it is possible to color the main substrate 2 easily and without fail.

Further, in detail, since the rear projection projector 300 has the above configuration in the present embodiment, it is possible to obtain excellent viewing angle characteristics and light use efficiency. Further, in detail, since the microlenses 21 each having a substantially elliptical shape are arranged on the above-mentioned microlens substrate 以 in a dog-tooth lattice manner, the rear projection type projector 300 hardly causes problems such as ripples. As described above, it should be noted that the member with the recessed portion 6, the method of manufacturing the member 6 with the recessed portion, and the member with the convex portion according to the present invention have been described with reference to the preferred embodiment shown in the drawings ( The microlens substrate 、), the transmissive screen 10, and the rear projection projector 300 are not limited to the embodiments. For example, a component that can perform the same or similar functions replaces each of the components (components) constituting the microlens substrate 1, the transmissive screen 10, and the rear projection projector. Further, in the above embodiment, even if spacers 20 each having a refractive index 106147.doc - 62 - 1295382 each having a refractive index almost equal to that of the resin material 23 (i.e., the resin material 23 after solidification) have been described as spacers However, in the area (non-use lens area) formed only by the first recessed portion 6丨 of the retracement .. ^ , , T, and the preparation part 6 with the concave portion, the shape of the object is required... The spacer 2 has a refractive index almost equal to that of the resin material 3 (i.e., the resin material 23 after solidification). Further, it is not always necessary to use the spacer 20 in the manufacture of a microlens substrate (a member to which a convex portion is attached). Further, in the above embodiment, even if the surface of the member 6 to which the resin material is attached with the concave portion has been described, the microlens substrate 丨 can be manufactured such that, for example, the resin material 23 is supplied onto the surface of the flat plate U and then The resin material 23 is pressed by the member 6 to which the recess is attached.

Further, in the above embodiment, it has been described that the second recess 62 has a lower density than the first recess. The density of 61. However, as long as the depth of each of the second recesses 62 is shallower than the depth of each of the first recesses 61, the second recesses 62 may be two-dimensional' and its shape, size, arrangement pattern Further, in the above embodiment, even in the above-described embodiment, each of the microlenses 21 in the microlens substrate (member with a convex portion) and the member 6 with the concave portion have been described. Each of the middle and concave phases has a flat shape (substantially circular shape) and/or a canine pattern, but the shape and/or arrangement pattern may be any shape and/or arrangement pattern. In other words, it can be arranged in a random manner. 'In the above embodiment, even though it has been described that the first region 67 is composed only of the first recess 106147.doc -64 - 1295382 61 and the second region 68 is composed only of the second recess 62, there may be a first mixed therein Further, in the above embodiment, even though each of the microlens 21 and the first recess 61 has been described as having a flat shape in which the vertical length is greater than its horizontal length, The shape of the microlens 21 and the shape of the first recess 61 are not particularly limited. For example, it may be, for example, a substantially circular shape, a substantially hexagonal shape, and a flat shape having a horizontal length greater than its vertical length. Any one of them.

Further, the second initial hole is formed in the same direction as the 幵 y Where the region of the first initial hole is formed and in the vicinity of the two ends of the soda lime glass substrate in the vicinity of the two ends, 1 〇emx65 em. The average width and the average length of each of the first initial holes are respectively 2 ·〇ιη&amp;2·2 μηι. Further, each of the second initial holes has an average width and an average length of 2.0 μm and 2.2 μm, respectively. In this respect, laser processing was carried out using YAG laser under the conditions of a beam diameter of 3 〇 μηη and a scanning speed of 〇·1 m/sec in the main scanning direction. Further, the energy intensity of the YAG laser is controlled such that it is 1 mW when the first initial hole is formed; and 1 mj when the second initial hole is formed. Further, the second initial hole is formed outside the region in which the first initial 106147.doc - 67 - 1295382 hole is formed by the second initial hole being gradually thinned toward the end of the longitudinal direction of the mother glass substrate. . In addition, at this time, each of the concave portions having a depth of about 〇·〇〇5 μm and one of the “(or a layer of the sounding layer) are formed on the surface of the nano-bow glass substrate in which the first initial hole is formed. "A corrosion-resistant one of the sealing members (such as a belt) is applied to the area of the mask #一= initial hole (corresponding to a second area). The adhesive member having a substrate formed of polyethylene terephthalate and an adhesive layer formed of an adhesive is used as the sealing member. Next, the sodium (tetra) glass substrate coated with the back protective film and the sealing member is subjected to a wet etching process. The second initial hole is exposed and brought into contact with the agent by removing the sealing member from the nanoma glass substrate in the middle of the wet money engraving process. The &lt;sodium sulphate glass substrate is subjected to a party-etching process, whereby a large number of dimples (recesses for forming microlenses) and a plurality of second recesses are formed on the main surface of the Namu glass substrate. Each of the two surfaces of the (four) glass substrate is substantially elliptical (flat), and the shape of each of the second recesses is substantially circular. The plurality of first-recesses thus formed have substantially the same shape as each other. The mother of the first recess formed: the length (diameter) in the direction of the short axis, the length of each of the formed first recesses in the direction of the long axis thereof, and each of the formed first recesses The radius of curvature and depth of one are 54 μΐΏ, 72 μηι, 37 〇, and 36.5 (4), respectively. Further, the density of the first recess in the usable area in which the first recess is formed is 260, _W. Further, the plurality of second recesses thus formed have substantially the same shape as each other. Each of the second recesses formed has a diameter and a depth of 47 〇 and 23, respectively. In the formation of the second recess 106147.doc -68· 1295382 乂 flute: the density of the first recess in the area is 100, 〇〇〇 / cm 2 . Further, the number of arrays of the second recesses in the second region is 7,_. In addition, the second recess: the average spacing of adjacent arrays is 1 〇〇 _. The length of the second zone in the direction of release is 50 mm. On this side, an aqueous solution containing 4 weight percent of diammonium hydrogenate and 8 weight percent of peracetic hydrogen was used as a money engraving agent for the wet residual process, and the substrate soaking time was 2.5 hours. Soil Next, an etching process (4) of the mask and the back protective film is carried out by using a mixture of cerium ammonium nitrate and perchloric acid. Next, it was washed with pure water and dried with nitrogen (N2) gas (for removing pure water). In this way, a substrate with a recess as shown in FIG. 4 is obtained, wherein the first recess having a large amount for forming the microlens is arranged in a dog-tooth lattice in the first region of one of the main surfaces of the nano-glass substrate. The second recess is arranged in the vicinity of the two ends of the soda lime glass substrate to form a first portion of the first recess such that it gradually becomes sparse outside the nanoglass substrate. When viewed from above one main surface of the soda lime glass substrate, the area (four) occupied by the first recess in the usable area (the first region) forming the first recess is 100%. Further, the ratio of the area occupied by the second recess in the usable area (second region) in which the second recess is formed is 50% when viewed from above one main surface of the soda lime glass substrate. Next, a release agent (GF-6110) is applied to the surface of the member with the concave portion of the first and second recesses formed thereon as described above, and the unpolymerized (uncured) layer is coated on the same surface side. Acrylic based resin (PMma resin (methacrylic resin)). At this time, the substantially spherical spacers 106147.doc-69-1295382 (each having a diameter of 20 μm) formed of a hardening material based on an acrylic resin (pmma resin (methacrylic resin)) are discharged.

The ratio of Cm aligns the spacers. At this time, it is used when the release is attached with a convexity. The member of the crucible (the cured resin material is assisted from the release of the member with the concave portion, and the release of the main substrate (the one provided with the convex portion provided on one end of the main substrate) is shown in the figure. 7). The width of the component used for assistance is 20 mm. (Secondly, the surface of the main body of the Thousand Plates, which was formed by the _ glass, was extruded (pushed) based on acrylic resin. At this time, the praise was made, and the I spear was made so that it was attached with a recess.

Between the piece and the acrylic-based resin, the helmet air is introduced, and the plate on which the surface is coated with the release agent (GF-6 110) is used as the plate. Next, the acrylic-based resin is cured to obtain the main substrate by heating the member to which the recess is attached. The obtained main substrate (i.e., cured acrylic-based resin) had a refractive index of 150. The obtained main substrate (except for the trowel forming the microlens) had a thickness of 22 μm. The length (pitch) of each of the formed microlenses in the short axis direction, the length of each of the formed microlenses in the long axis direction thereof, and the curvature of each of the formed microlenses The radius and depth are 54, 72, 37.5 and 37〇, respectively. Further, the ratio of the area occupied by the microlens in the available lens area for forming the microlens is 100%. The cured acrylic based resin has a hardness of 5.4. Second, the autonomous substrate removes the plate. /, a person who added a positive type photopolymer (PC405G: manufactured by JSR Corporation) to which a light-screen material (carbon black) is added, is supplied to the light-emitting surface of the main substrate by means of a roll coater (for which a light-emitting surface has been formed) The surface of the surface of the microlens). The content of the light-shielding material in the photopolymer was 20% by weight. Next, the main substrate was subjected to a 90 x 30 minute pre-bake process. 106147.doc -70- 1295382 Next, ultraviolet rays of 80 mJ/cm 2 were irradiated as parallel light through the surface of the surface on which the concave-attached member on which the concave portion was formed. Thus, ultraviolet rays are irradiated by each of the microlenses, and photopolymers are selectively exposed in the vicinity of the focus f of each of the microlenses (near the center in the thickness direction of the black matrix to be formed). The main substrate having the member with the recessed portion was subjected to a developing process for 40 seconds using a 0.5 wt% aqueous solution of K〇H. Next, it was washed with pure water and dried with N 2 gas (for removing pure water). In addition, the main substrate was subjected to a -20 〇tx3 〇 minute lapse process. Thus, a black matrix having a plurality of openings respectively corresponding to the microlenses is formed. The thickness of the formed black matrix is 5. 〇 μηι. The main substrate is then released from the member to which the recess is attached in the following manner. First, the member for assisting the release of the main substrate is removed from the member to which the recess is attached&apos; and the member is also removed from the main substrate thus formed. The main substrate is bent by pulling one end of the main substrate, and the main substrate is continuously (without interruption) released at a predetermined constant speed. The release direction is set to the first recess: the short axis direction of each (i.e., the longitudinal direction of the main substrate). At this time, the tensile strength was again set to 8 〇g/cm (width), and the release catch was set to 20 _ / sec. Ceremony::: Helps the dip dye to apply the colored liquid to the main substrate that has been released from the member with the recess. Implementing this temptation, the main "匕裟釭" is such that although the entire surface is formed to contact the colored liquid, the black matrix formed thereon does not contact the colored liquid. Further, when the colored liquid is supplied to the main substrate and The temperature of the coloring liquid is adjusted to (10), and the pressure in the liquid supply process is HM, (, Futaba San^ 1 π 50 · 2 parts by weight, disperse dye (red 106147.doc 1295382 color) (manufactured by Futaba Sangyo) ): 〇" parts by weight, disperse dye (yellow) (by

Futaba Sangyo): 0,05 parts by weight, benzyl alcohol: 1 part by weight, interfacial activity agent: 2 parts by weight, and pure water: 1 part by weight of a mixture as a coloring liquid. After the main substrate was contacted with the colored liquid for 2 minutes under the above conditions, the main substrate was taken out from the tank in which the colored liquid was stored, and then the main substrate was washed and dried. The microlens substrate in which the coloring portion has been formed is obtained by washing the main substrate with pure water and drying the main plate by gas (for removing pure water). The colored portion thus formed had a color density of 7 Å/〇. Further, a total of (10) microlens substrates are manufactured by repeatedly performing a similar process using a member with a recess as described above. Next, the penetrating corpse shown in Fig. 3 was fabricated using the first microlens substrate and the hundredth microlens substrate.
